A-06 Preferred Sources must be used only on eligible sites, as a user preference feature

Why it matters
If a site that is not eligible adds the feature, or claims it lifts rankings, users are misled and the team wastes effort on something that does not do what is promised. Preferred Sources is a way for people to choose the sources they see, not a ranking lever. Treating it that way keeps expectations and reporting honest.
How to implement
- Check domain or subdomain eligibility in the source preferences tool before doing anything else.
- Turn on Search generative AI inclusion if you are targeting AI features.
- Add Google's official Preferred Sources button only where the site is eligible.
- Move the button to a place where it is useful and does not get in the way.
- Track adoption and report it as a user preference measure, not a ranking gain.
Checklist
- Verify the eligibility of the domain or subdomain in the source preferences tool.
- If AI features are the target, Search generative AI inclusion must be switched on.
- Where eligible, use Google's official interactive Preferred Sources button implementation.
- Show the button in sensible places where it does not annoy users.
- Measure adoption, and do not present it as a general ranking boost.
How to audit
- Check that eligibility has been confirmed for the domain or subdomain.
- Check that the button uses Google's official implementation and sits in sensible places.
- Check that no copy or reporting describes Preferred Sources as a ranking boost or mandatory factor.
How UltimateSEO checks this automatically
This control needs human evidence: whether the site is eligible for Preferred Sources and how it is presented to users.
States used: PASS, FAIL, UNKNOWN, NOT_APPLICABLE or BLOCKED. UNKNOWN is never shown as a pass. How states work.
